Home Automation water Tank: common questions
What microcontroller does the Home Automation water Tank use?
The Home Automation water Tank is built around the ESP32-C3-WROOM-02, from the ESP32 family.
How big is the Home Automation water Tank PCB?
The Home Automation water Tank measures 40.6 × 50.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Home Automation water Tank?
26 components, from 16 distinct parts. The full bill of materials is listed on this page.
Where can I download the Home Automation water Tank design files?
From the rajeev2705/PROJECTS repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Home Automation water Tank design in my own project?
The repository has no license, so all rights stay with rajeev2705. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Home Automation water Tank without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
